Notes: This script summarizes the key output values from Slicer, for all tracts. We have data for n=35 tracts (n=62 unique combinations with hemisphere). We expect to have data from n=41 tracts.

The data we have available is summarized below (collapsed across all sites):


Data summary.

Missing tracts. The count variable in the table above indicates the number of participants with data for a given tract, and percent indicates corresponding percentage. In total, we have data for 16358 tracts out of a possible maximum 27032, i.e., 60.5134655%.

Visualization: Number of Fibers.

The following plot shows the number of raw data for the number of fibers variable from the n=436 participants summarized above, separated by tract and hemisphere (n=74). Outlier values will be apparent.
